hghave: add cvsnt
cvsnt is a maintained commercial fork of cvs
https://en.wikipedia.org/wiki/CVSNT
It is possible to build a version of it from sources (github),
it requires libpcre and libltdl (libtool).
We already have a test that relates to cvsnt:
test-convert-cvsnt-mergepoints.t
cvsnt installs: cvs, cvslockd, cvsnt, cvsscript
I think we should definitely have a check for cvsnt because it makes
the version checks for cvs make a lot more sense.
When I use the version I built, cvs --version says:
